Answer:
Yes the car was speeding
Step-by-step explanation:
s = √(30fd) where
- s is the speed of the car in mph
- f is the coefficient of friction for the road
- d is the length in feet of the skid marks
Substitute d = 41.5 and f = 0.8 into the equation:
s = √(30 x 0.8 x 41.5)
⇒ s = √(996)
⇒ s = 31.55946768...
Therefore, for these data, the speed of the car was 31.56 mph (to the nearest hundredth)
The speed limit was 30 mph, therefore the car was speeding as 31.56 > 30
